 note = {At 10:42:59 UT, 18 November 2001, a -3 magnitude Leonid meteor was recorded withan intensified CCD imager at 1000 frames per second. The observation was made at Poker FlatResearch Range north of Fairbanks, Alaska. The high-speed imager covered the main brighteningphase as the Leonid descended from an altitude of 115.6 km to 104.4 km. With millisecondresolution there is no "smearing" due to meteor motion. Below 111 km a large, several 100 mwide, shock-like structure developed. Such structure has not previously been reported. The size issurprisingly large and cannot be explained by classical fluid dynamics. We speculate that additionalprocesses driven by intense UV radiation from the heated meteor core leading to photo ionizationof the ambient air may play an important role., 資料番号: SA4653344000},
